A last name of German origin that no one can seem to pronounce correctly on the first try. Other interpretations include "Ja-NOOSH" and "Jah-NUSH." Both of these, while fun, are incorrect. Proper pronunciation is "Jan-ISH."
"Dude, that girl's last name was something freaky. I think it's pronounced 'Ja-NOOSH.'"
"Jannusch? It's 'Jan-ISH' you tool."
